IMPRovEMENT 1N LAMPS.

Specification forming part of Letters Patent No. 122,864, dated January16, 1872.

To all whom it may concern:

Be it known that I, WILLIAM STAEHLEN, of Williamsburg, Kings county,State of New York, have invented an Improvement in Lamps; and thefollowing is declared to be a correct description of the same.

This invention applies to the class of lamps in which there is anelevated fountain and a standard carrying a shade-ring and shade.

I make use of a fountain of sheet metal, made of two conical shells withthe edges folded and soldered to lessen risk of leakage. The standardcarrying the shade-ring is grooved to take the end of theclamping-screw, thereby retaining the shade-rin g in position andpreventing turning. The base of the lamp is only weighted on one side tocounterbalance the reservoir and prevent the lamp tipping either when atrest or while being moved from place to place; and a clamping-ring isapplied where the burner-case screws to the base, so as to hold theparts in the correct relative position for bringing the weight of thebase on the opposite side to the reservoir.

In the drawing, Figure l is an elevation, partially in section, of thelamp. Fig. 2 is an inverted plan of the base; and Fig. 3 is a sectionalplan in larger size of the standard and part of the shade-ring.

The fountain or reservoir is made of two frustums, a and b, of sheetmetal, with the edges folded together and then soldered at o. The upperpart b may be more or less ornamented by coves and ribs spun or stampedup in the metal. A-valve, d, is inserted for the usual purpose, and theneck at this lower end of e, instead of being soldered on, asheretofore, is made out of the same metal, thereby avoiding risk ofleakage. The fountain-holder c is at one end of the tube f, and theother end of the tube f is connected to the burnercase h, screwing andsoldering or brazing being resorted to to make a firm attachment. Theburner-case h is to be of any desired size to contain the liquidhydrocarbon for the burner, and the burner itself may be within thiscase or screwed upon it. and may be either a flat wick or an argandburner. The base k of the lamp is of suitable size and shape; but thecounterpoise l is only in one-half th ereof, upon the side opposite tothe reservoir a b, so as to` make the lamp stand firmly and use aslittle weight of material as possible, to avoid making the lamp tooheavy for transportation with facility. The case h screws upon the basek, and in order to hold the parts in the proper relative position withthe weight l opposite to the reservoir a clamping-ring, u, is introducedto screw down against the upper end of 7c and prevent the parts turning.The standard 'm receives the slide o and clamping-screw p of theshade-ring q. In order to prevent the shade-ring turning and strikingthe lampchimney, and injuring the same, I make use of a channel runningalong the standard m and receiving the end of the screw p. Thereby thering q will be guidedby the end of the screw when being raised orlowered, and then clamped by simply turning said screw.

I am aware that cylindrical reservoirs have been made with a cylindricalneck soldered to the lower end, as in the patent of O. A. Kleeman, March10, 1863.

In my reservoir the lower section, being a conio frustum, allows of thesame being made out of one piece of sheet metal, including the neck,thereby avoiding risk ot' leakage.

I do not claim a lamp-base made heavieron one side than the other.

I claim as my inventionl. The lamp-reservoir made of the parts a bunited together, the part a. being made as a frustum of a cone, with theneck at its lower end of one piece of sheet metal, for the purposes setforth.

2. The burner-case h screwed upon the base k, and carrying the tube eand fountain, in combination with the oounterpoise Z in the base k atthe opposite side to the fountain, as set forth.

3. The ring u upon the screwof the case 7L, between the same and thebase 7c, for clamping the parts, in combination with the weighted base land reservoir a b, as set forth.

4. The grooved standard m, in combination with the shade-ring q andscrew p, as and for the purposes set forth.

Signe l by me this 4th day of October, A. D. 1871.
